The ride height of each vehicle varies due to the condition and trim
model of the vehicle. The optimal way to determine which kit you require to
level your truck is to park your vehicle on a level ground and take a
tape-measure in order to measure the distance from the ground to the top center
of the fender arch. Take the measurements for both the rear and front and
subtract the two numbers. This is about the amount you will need in order to
perfectly level your vehicle.
